What It Is

This is a set of two 42-inch replacement mower blades designed for select Troy-Bilt, Cub Cadet, and MTD tractors with a 42-inch cutting deck. They are intended for regular mowing of grass on residential lawns.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches (measured blade tip to blade tip). These blades use a 6-point star center hole (not a standard oval or keyhole) – critical for fitment on spindles with a star-shaped drive hub. Compatible models include Cub Cadet LT42, LT4200, XT1-42, RZT42, and Troy-Bilt equivalents. Cross-references OEM part numbers: 942-04308, 942-04308A, 942-04308-X, 942-0616A, 742-0616A, 742-0616, 942-0616, 112-0315. Do not assume fit based on brand alone – measure your existing blade length (tip to tip) and verify the star pattern matches your spindle.

Key Things to Know

• Aftermarket quality: These are not OEM Cub Cadet blades, but rated 4.4/5 from 46 reviews. Expect adequate sharpness and balance for residential use, but may dull faster than OEM.
• Installation difficulty: Easy – lift deck, block securely, remove center bolt with a wrench, swap blades. Torque the center bolt to 70-90 ft-lbs. Use thread locker if specified by your deck manual.
• Common gotcha: The star center hole must align perfectly with your spindle’s drive star. If your spindle uses a different hole shape (e.g., diamond or oval), these blades will not work.
• Pack size: Two blades included – enough for a standard two-blade 42-inch deck. No hardware (bolts, washers) included; reuse your original hardware if in good condition.

Should You Buy It

Buy these if you have a 42-inch Troy-Bilt or Cub Cadet with a 6-point star spindle and want a budget-friendly 2-pack for regular residential mowing. Skip them if you need OEM durability for heavy use, commercial duty, or if your deck uses a non-star spindle pattern.
